I love my Apple Wireless Keyboard, but I don’t love changing its darn batteries every couple of weeks. But the Logitech K760 Wireless Solar Keyboard could soon be taking its place on my desk. Powered entirely by ambient light (it doesn’t even need batteries as a backup), the K760 will run for three months on a full charge with eight hours of use a day.

It’s ideal for those with Mac and iOS devices, because it allows you to connect to three devices simultaneously and quickly switch between them using the function keys.
